What is ListDefender?

ListDefender provides everything you need to verify, clean, and maintain your email lists with AI-powered form protection, email verification, and engagement tracking.

We love recommending tools that genuinely make our lives easier, and ListDefender is one of those tools. It’s built by our friends over at PlusThis who have earned our trust over and over.

Everyone knows that keeping your email list clean is a must have best practice these days, but it still isn’t as easy as it should be.

You need one tool to clean your list, then an integration for that tool to connect to Keap or Highlevel, another tool to protect your forms, and on top of this some kind of email engagement reporting and updating tool.

Womp womp. Not very fun.

ListDefender was developed to fix this by giving you list cleaning, form protection, and email engagement tracking with one tool.

Yes, we are affiliates, and yes, we’d love it if you used our link when you sign up (here’s the link), but that’s not why we’re recommending it.

We’re recommending it because it works.

If you’ve ever wondered if your forms are being abused by bots, or if you’re accidentally sending to contacts who haven’t opened in years, ListDefender helps you spot and stop those issues—before they hurt your sender reputation.

You can have ListDefender running inside Keap or HighLevel in just a few minutes—and once it’s live, it runs in the background like a smart little bouncer for your email list, keeping the junk out and letting your best leads in.
